Abstract

PURPOSE:To alarm a dangerous condition where a driver leaves his seat to open the door without stopping the engine or in the geared condition, or an automobile moves automatically when the driver leaves from his seat in the automobile having an automatic transmission. CONSTITUTION:Respective terminals of an alarm device such as a chime 10 having terminals which are electrically short-circuited (ON), a switch 13 to be short-circuited (ON) when a transmission lever is selected to other than P(parking), and a switch 14 which is short-circuited (ON) when the door aside the driver's seat is opened are electrically connected in series by means of electric wires. Alternatively, the switch 14 which is short-circuited (ON) when the door aside the driver's seat is opened may be relocated to the lower part of the driver's seat, and short-circuited (ON) when the driver leaves his seat.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety device for an automobile having an automatic transmission.

[0002]

2. Description of the Related Art Conventionally, in an automobile having an automatic transmission (hereinafter sometimes simply referred to as an AT vehicle), there is an alarm device for an automobile which warns when a shift lever is selected to R (reverse). . This tells the driver that the shift lever is R
It was just a recognition that they were selected for (regression).

[0003]

The AT vehicle is equipped with a side brake when the engine is rotating and the shift lever is selected to D (forward) or R (reverse), that is, when the gear is engaged. When the foot brake is released, it has a characteristic called creep phenomenon in which the car starts moving slowly without pressing the accelerator pedal (without increasing the engine speed). Until now, there was only an alarm device that warns only when the shift lever is selected to R (reverse) as in the preceding paragraph. Therefore, without stopping the engine and with the gears in place, even if the driver opens the door to leave the seat without sufficiently applying the side brakes, there is no warning and the car does not notice the slow-moving car. However, there was a problem that it could lead to a big accident. Therefore, the present invention is
The present invention has been made to solve the above problems, and when the shift lever is selected other than P (parking), the chime is opened when the door beside the driver's seat is opened or when the driver leaves the seat. It is a safety device that warns the driver of the situation and prevents the driver from leaving the seat as it is.

[0004]

The present invention has the following constitution in order to achieve the above object. That is, an alarm device such as a chime 10 having a terminal that is electrically short-circuited (ON) to operate, a switch 13 that is short-circuited (ON) when the gearshift lever is selected other than P (parking), and a driver seat side It is characterized in that each terminal of the switch 14 which is short-circuited (ON) when the door is opened is electrically connected in series by an electric wire. In addition, a switch 14 that is short-circuited (ON) when the door beside the driver's seat is opened is installed under the driver's seat so that it is short-circuited (O) when the driver leaves the seat.
N) may be performed.

[0005]

When the switch 13 attached to the shift lever portion and the switch 14 attached to the door portion or the driver's seat portion are both short-circuited (turned on), that is, the shift lever is selected other than P (parking). However, when the driver opens the door beside the driver's seat or the driver leaves the seat, the chime alerts the driver, so the driver leaves the car with the shift lever selected other than P (parking). There is no end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a view showing the structure of an automobile alarm device according to the present invention and an embodiment in which this device is attached to an AT vehicle. Reference numeral 10 is a chime, and power is supplied through an electric wire 12 by inserting a plug 11 into a socket 21 for a cigarette lighter of an automobile. Chime 10
Sounds when the terminals 11a and 11b are short-circuited. Reference numeral 13 is a switch, and the terminals 13a and 13b are opened only when the rod portion 13c is pushed. This switch 13 is fixed to the P (parking) side of the transmission 23 of the automobile with a double-sided adhesive tape or the like, and the rod portion 13c is pushed by the gear shift lever 22 only when the gear shift lever 22 is set to P (parking), and the terminal 13a
And the terminal 13b are opened, and the rod portion 13c is not pushed when the position is other than P (parking), the terminals 13a and 13b are short-circuited. 14 is also a switch for the rod portion 14
Only when c is pushed, the terminals 14a and 14b are opened. When the switch 14 is attached to the door portion, it is fixed to the vehicle body side 25 of the driver's seat side door of the automobile with a double-sided adhesive tape or the like. Therefore, when the driver's side door 24 is closed, the rod portion 14c does not move to the door 2
4, the terminals 14a and 14b are opened, but when the door 24 is opened, the terminals 14a and 14b are opened.
b is short-circuited. When the switch 14 is attached to the driver's seat, it is installed inside the driver's seat 26 as shown in FIG. 2, and when the driver is sitting on the seat, the rod portion 14c is pushed by the weight of the driver. Thus, the terminals 14a and 14b are opened, but when the driver leaves the driver's seat 26, the terminals 14a and 14b are short-circuited.
FIG. 3 is a cross-sectional view showing the structures of the switch 13 and the switch 14. Since the switch 13 and the switch 14 have the same structure, they will be described in the same drawing. Rod portion 13c (14
When c) is not pushed, the spring 13d (14
The contact 13e (14e) and the contact 13f (1
4f) is urged in the direction of contact, and the rod portion 13
When c (14c) is pushed, spring 13d (14d)
Contact point 13e (14e) and contact point 13f against the biasing force of
(14f) is open. 4 is shown in FIG.
2 is an electric circuit diagram of the automobile alarm device of FIG. As is clear from this electric circuit diagram, the switch 13 attached to the transmission unit is ON, that is, the transmission lever 22 is at a position other than P (parking), and the switch 14 attached to the door portion or the seat portion.
Is ON, that is, when the door is open or the driver is not sitting in the seat, the chime 10 will ring.
Since the driver who receives the warning by the chime leaves the vehicle at least with the speed change lever in the P (parking) position, the vehicle does not start due to the creep phenomenon and the safety can be ensured. The automobile alarm device may be attached to the completed automobile as in the above embodiment, or may be incorporated in the automobile at the time of producing the automobile. Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, the switch 13 or the switch 14 may be a switch using an infrared sensor.
Needless to say, many modifications can be made without departing from the spirit of the invention.

[0007]

When the vehicle alarm device according to the present invention is used, when the driver leaves the seat without stopping the engine in an AT vehicle, the transmission lever is erroneously changed to a gear such as D (forward) or R (reverse). If the car is left in the state where the car remains in the car, there is a danger that the car will start moving by itself, but the driver is in a dangerous condition because the chime etc. warns when there is such a danger. Since the shift lever is set to P (parking) upon recognizing that, an accident can be prevented.
